Objective: To determine the perinatal and maternal characteristics in patients with post-term pregnancy diagnosis at general hospital. Material and methods: Retrospective study, cases series type, conducted at the Hospital National Cayetano Heredia in Lima, Perú from January 1°, 2000 to December 31, 2004. We included 341 patients with a post – term pregnancy (EP) diagnosis based on trust LMP or first trimester ecography. The data was processed in SPSS 13 program. Results: 76% of patients were 20 to 35 years old, with a mean of 25.8 ± 6.1. The 47.5% of patients had no previous deliveries. After the first evaluation, 71.3% of patients had already began spontaneous labor; 16.4% were induced, and 12.3% had cesarean section indication. From the spontaneous labor group, 71.6% had a spontaneous vaginal delivery; 19.3% had a cesarean section, and 9,1% had a vaginal operative delivery. From the induced group, 71.4% had a spontaneous vaginal delivery, 23.2% had a cesarean section, and 5.4% had a vaginal operative delivery. 62% had a final vaginal spontaneous delivery, 29.9% had a cesarean section, and 7.4% had a final vaginal operative delivery. The newborns (RN) were adequate for the gestational age in 85.9%; 11.1% were big for their gestational age, and 3% were little for gestational age. 53.4% of newborns were 37-41 weeks by Capurro, 45.7% were>42 weeks by Capurro, and 0.9% were < 37 weeks. The 5 minute Apgar was 7 to 10 in 333 RN, < 7 in 4 RN; and there were 4 stillbirths cases. Conclusion: The post – term pregnancy had a higher incidence in adult and nulipare patients. Most of the patients began a spontaneous labor, and the vaginal delivery route was the most frequent. There was a low rate of complications in alive RN, but there was a high mortality rate as well. The cesarean sections indications were CPD and fetal distress. (Rev Med Hered 2009;20:200-205).
